摘要翻译：
本文证明了Kontsevich在研究Witten猜想时引入的模空间的某种自然紧致的同调可以完全代数地描述为某种微分分次李代数的同调。这个双参数族是利用非对易0-型空间上的一个李协括号构造的，它对应于黎曼曲面上简单闭曲线的捏缩，从而使Kontsevich在随后的论文中所描述的非对易辛几何变形。

英文摘要：
In this paper we show that the homology of a certain natural compactification of the moduli space, introduced by Kontsevich in his study of Witten's conjectures, can be described completely algebraically as the homology of a certain differential graded Lie algebra. This two-parameter family is constructed by using a Lie cobracket on the space of noncommutative 0-forms, a structure which corresponds to pinching simple closed curves on a Riemann surface, to deform the noncommutative symplectic geometry described by Kontsevich in his subsequent papers.
